L-Adenosine is a metabolically stable enantiomeric analog and also is a potential probe. L-Adenosine has weakly inhibitory adenosine deaminase (ADA) activity with an Ki value of 385 μM. L-Adenosine can be used for the research of adenosine uptake and accumulation[1].
L-Adenosine (10-10,000 μM) weakly inhibits rat brain adenosine deaminase (ADA) activity with an Ki value of 385 μM[1].
